Tuesday afternoon between 3 p.m. and about 4:15 (depending on who you ask) Lewisville police tried to make contact with a woman who was reported missing after she failed to show up for work for a couple of days. When police went to the home in the 1600 block of Chisolm Trail to check the woman's welfare, a man believed to be her husband answered but refused to cooperate with police.

SWAT had been called to the residence, and numerous emergency responders were staged along Garden Ridge.

Lewisville Police Captain Kevin Deaver said Tuesday night that the suspect had not communicated with police, despite having been thrown a phone earlier in the afternoon. Deaver said that no weapons had been spotted, and that they had not made contact the missing woman. Throughout the afternoon, a voice could be heard on a loudspeaker encouraging "Michael" to come out.

Here's video of police making entry to throw in a device. A hostage negotiator was on scene.

Update: We have the name of the homeowner. A basic criminal records check shows no history.

Update: 9:54 p.m. Unconfirmed reports via Twitter that the woman is dead and the man has been arrested. Trying to get confirmation.

Update: 11:24 p.m. All major news outlets were reporting that the woman was dead. We hope to have more information from LPD tomorrow. We believe this is the first murder in Lewisville for 2012. The last one was in December 2011 when Trevor Matthew Kronbach was killed during a robbery at Park Lake One apartments.

Update: 8:07 a.m. we have a mugshot of the suspect, 76 year old Michael Stolz, who has been charged with murder:
